Abstract
A method performed by a location management function (LMF) in a wireless communication system, according to an embodiment of the present disclosure, may include obtaining downlink positioning reference signal (DL PRS) configuration information, determining, at least based on the obtained DL PRS configuration information, a need for on-demand DL PRS configuration information, and, in case that it is determined that the on-demand DL PRS configuration information is needed, transmitting the on-demand DL PRS configuration information to a user equipment (UE).
Claims15
A method performed by a location management function (LMF) in a wireless communication system, the method comprising:
- obtaining downlink positioning reference signal (DL PRS) configuration information;
- determining, at least based on the obtained DL PRS configuration information, a need for on-demand DL PRS configuration information;
- and
- in case that it is determined that the on-demand DL PRS configuration information is needed, transmitting, to a user equipment (UE), the on-demand DL PRS configuration information.
A location management function (LMF) communicating a user equipment (UE) in a wireless communication system, the LMF comprising:
- a transceiver;
- and
- a processor operatively coupled to the transceiver and configured to
- obtain downlink positioning reference signal (DL PRS) configuration information,
- determine, at least based on the obtained DL PRS configuration information, a need for on-demand DL PRS configuration information, and
- in case that it is determined that the on-demand DL PRS configuration information is needed, transmit, to the UE, the on-demand DL PRS configuration information.
A method performed by a user equipment (UE) in a wireless communication system, the method comprising:
- receiving downlink positioning reference signal (DL PRS) configuration information from a location management function (LMF);
- transmitting, based on the received DL PRS configuration information, a request for on-demand DL PRS configuration information to the LMF;
- and
- receiving, from the LMF, the on-demand DL PRS configuration information in case that it is determined by the LMF, based on the request for the on-demand DL PRS configuration information and the DL PRS configuration information, that the on-demand DL PRS configuration information is needed.
